Complicated axillary lymphadenectomy due to a pectoralis quartus muscle.

چکیده
During lymphadenectomy in the left axilla of a 38-year-old woman with a 1.4 cm invasive ductal breast carcinoma an accessory muscle was found. Due to the presence of the anomalous muscle the lymphadenectomy was carried out with difficulty through a limited field. Based on its anatomical characteristics, the supernumerary muscle was recognized as the pectoralis quartus. To our knowledge this is the first report of a pectoralis quartus muscle as a surgical finding. The surgeon should be aware of the possible presence of this anomaly as well as its anatomical characteristics in order to avoid any complications.

Unilateral presentation of three muscle variants in the pectoral region
A rare case of three muscle anomalies in the pectoral region was discovered during routine dissection of an 85-year-old female cadaver. The muscle anomalies include the congenital partial absence of the pectoralis major muscle, a sternalis muscle, and a pectoralis quartus muscle. All three variants presented on the right side. The pectoralis major muscle demonstrated a normal clavicular head bu...
متن کاملThe morphology and clinical importance of the axillary arch.
The axillary arch is the main variation of the axillary muscle. It was first described by Ramsay in 1795. In its classical form, it arises from the latissimus dorsi muscle and extends from this towards the pectoralis major, crossing the base of the axilla and creating a close relationship with the elements of the axillary neurovascular bundle. We describe the finding of 9 axillary arches, inclu...

Langer's arch is the best-known anatomic variant of definite surgical implication in the region of the axilla. This rare anomaly is a muscular slip extending from the latissimus dorsi (LD) muscle to the tendons, muscles or fasciae around the superior part of the humerus. In this report, we present a rare case of left axillary arch. During modified radical mastectomy for breast cancer, we encoun...

IntroductIon The muscle mass of the pectoral region exhibits a variety of variations in the form of anomalous slips. The pectoralis major muscle is a thick triangular muscle that usually arises from the medial half of the clavicle, the sternum, and the first six costal cartilages. These three heads, the clavicular, the sternocostal and the abdominal, combine to form a tendon that inserts into t...
متن کاملAn accessory muscle of the thoracic wall
Introduction Customary dissection in the Physical Therapy Anatomy Laboratory yielded a unilateral left-sided pectoral variation in a single cadaver. The cadaver was a 60-yearold Caucasian male. The variant included two separate thoracic wall muscles between the pectoralis major and pectoralis minor muscles. One muscle was identified as a pectoralis quartus and the other as an accessory thoracic...
